XP052011089 discloses that scheduling PDSCHs on multiple carriers via a single DCI: Regarding using a single DCI scheduling two PDSCHs on two carriers, there are two possible cases, Case 1: one PDSCH is self-scheduled on same carrier and another PDSCH is cross-carrier scheduled; Case 2: the two PDSCHs are cross-carrier scheduled from a third carrier.
